摘要： An apparatus for removing condensed water of an intercooler includes a collecting portion for collecting condensed water, the collecting portion being provided at a lower end of the intercooler; and an ultrasonic wave vibrator provided in the collecting portion, the ultrasonic wave vibrator being operated to introduce the condensed water collected in the collecting portion toward an engine so that the condensed water is vaporized, thereby removing or significantly reducing an amount of condensed water in the intercooler. The apparatus for removing condensed water of the intercooler can prevent engine damage and ignition failure due to the presence of the condensed water in the intercooler.

摘要： An apparatus for correcting a torque model of a spark ignition engine and a method thereof are disclosed. The apparatus includes: a driving information detecting unit which detects engine information and environment information of a vehicle, a combustion pressure sensor which measures a combustion pressure inside a cylinder of an engine, and a controller controlling the engine. In particular, the controller controls the engine based on a pre-stored HR50 (heat release 50%)-based torque model according to whether the combustion pressure sensor of the engine is abnormal or based on an ignition timing-based torque model corrected based on the combustion pressure detected by the combustion pressure sensor with respect to a pre-stored ignition timing-based torque model.

摘要： A method of controlling an electric continuous variable valve timing apparatus improves starting performance of an engine by a simplified phase control for the camshaft. The method, in which intake and exhaust timing of an engine is changed in accordance with a phase of the camshaft, may include: determining whether starting off of the engine is required during driving; recognizing a target phase of the camshaft for next starting of the engine; controlling the phase of the camshaft so that the intake timing of the engine is advanced in accordance with the target phase; and ending the phase control of the camshaft in accordance with a state of the engine or the camshaft.
